Welles: Among those whom I would call ‘younger generation’ Kubrick appears to me to be a giant.
Interviewer: But, for example, The Killing was more or less a copy of The Ashphalt Jungle?
Welles: Yes, but The Killing was better. The problem of imitation leaves me indifferent, above all if the imitator succeeds in surpassing the model . . . What I see in him is a talent not possessed by the great directors of the generation immediately preceding his . . . Perhaps this is because his temperament comes closer to mine. - Orson Welles, from a 60's interview in Cahiers du Cinéma

He was a friend and I loved and revered him. I think that my favourite moment is Peter Bull as the Soviet ambassador and the fight with Peter Sellers as Dr Strangelove. It was that improvised, half-assed, completely brilliant aspect of Stanley that I loved the most. Then, later, he became the opposite: he had to have total control over everything, doing 500 takes just to get it right. It was another kind of genius, but it would never have permitted those moments of improvised mastery that were in “Strangelove”. In the end, I think he began to have trouble, because if you can’t leave home, you lose track of reality, and I think that happened to him. Still, he made great movies and he was a completely gifted director. If you look at “2001: A Space Odyssey”, you suddenly realise: My God, there’s nobody in this movie! There are those two guys who you can’t quite tell apart as they have no real characteristics, and the rest is just… Well, what is it?! - Mike Nichols

I admire Kubrick greatly. He is often accused of being a prodigious technician and rigid intellectual, which people say makes his films very cold. I don’t agree. I think that "Barry Lyndon" or "A Clockwork Orange" are the most perfect marriages of personality and subject. - Guillermo del Toro
